I have a Tablo Dual Lite (version 2 I think) model TDNS2B-01-CN.
I’m getting this message: “Player Error Could not complete request (503)”.
In troubleshooting, I finally figured out if I disconnect the Seagate 2TB USB drive it goes back to working fine. My assumption is the drive has just gone bad and I need to buy a replacement. Does that sound right?
It’s worth touching base with support for some additional troubleshooting to see if the drive can be saved or if something else might be at play: www.tablotv.com/support/
Just to follow up in in case someone else stumbles upon this … at least for me, a new external USB drive fixed the problem.
Interestingly, I hooked the old supposed-bad drive up to one of my windows PC’s and and was able to reformat it and it’s now working fine in the Windows environment.
Years ago a USB drive on my Tablo just wasn’t working right, so I replaced with another drive (SSD) and no more problems.
Same as you I connected the swapped out (“bad”) drive to a Windows PC, still running good. I didn’t think of it at the time, but it may have been power related (weak Tablo power supply or the hard drive drawing more than nominal power?).
